What does it mean by binding / rebinding. Does it mean to link the relay and the wireless stat together? In a way a bit like hooking up a laptop to a wireless internet box via the IP addresses etc?
Yes. All devices will work in the same frequency band, but each one has a different address; it's a case of matching addresses. I would assume that one of the pair has a fixed address, so binding just makes the other item sweep through all possible addresses until it gets a match.
Also what does it mean by heat/cool changeover please?
Yes it will work, but the relay will only be powered when the timer turns the heating on. This is not recommended as the relay has to set up communication with the transmitter each time it turns on.
I have a thermostat that I foolishly failed to consider when wall mounting a TV nearby.
Surprise surprise heat from the TV affects the temp of the thermostat.
A boiler engineer recently suggested installing a wireless thermostat where the receiver simply replaces the existing thermostat.
Is this possible?
This sounds too easy, especially when almost all the other advice online suggests installing the receiver close to the boiler.
